Motorized molecules activated by light target and drill through highly antibiotic resistant bacteria and kill them within minutes. The molecules can open bacteria to attack by drugs they previously resisted. The strategy could be applied to bacterial infections or diseases on the skin, in the lungs or in the gastrointestinal tract.

A team of researchers has found that neural exosomes -- 'cargo' molecules within the nervous system that carry messages to the brain -- can minimize or even avert progression of traumatic brain injury when used as part of a new cell-to-cell messaging technology.

Nipah virus, which is transmitted to humans from bats and pigs, has a high mortality rate and there are no licensed drugs against it. Now, researchers have used information on the structure of the Nipah virus to identified 150 possible inhibitors of the virus.

Researchers have shed light on how the parasite which causes sleeping sickness multiples inside its host. Human African Trypanosomiasis or sleeping sickness, only occurs in Sub-Saharan Africa where an estimated 60 million people in 36 countries are at risk. The infection attacks the central nervous system and is fatal without treatment. Researchers have found that the parasite's cell division differs from that of humans and animals.

A computational study by chemists showed the dynamics of tumor formation don't necessarily correlate with clinical data on lifetime cancer risks. It suggests biomarkers may someday be able to help predict when mutations in cells will turn cancer-prone cells into full-blown cancer.

Colon cancer cells deficient in p53, one of the most important control proteins in cell growth, activate a particular metabolic pathway to adapt to the lack of oxygen and nutrients inside the tumor. Statins, which are often prescribed to lower cholesterol, block this metabolic pathway and cause the cancer cells to die, as scientists have now discovered. The researchers now intend to investigate this potential treatment strategy in more detail in cancer cells and animal experiments.

Researchers showed, for the first time, that a single, higher dose of vaccination to a pregnant mouse safely protects both her and her fetus from the Zika virus. The researchers found that a single, less potent dose was not enough to protect the fetus.

Someday, doctors would like to grow limbs and other body tissue for soldiers who have lost arms in battle, children who need a new heart or liver, and many other people with critical needs. Scientists are supporting this field of research by developing a promising new kind of light-based sensor to study tissue growth in the lab.

A new study from a team of clinical psychologists suggests eating added sugars -- common in so many holiday foods -- can trigger metabolic, inflammatory and neurobiological processes tied to depressive illness.

Scientists have known for decades that aerobic exercise strengthens the brain and contributes to the growth of new neurons, but few studies have examined how yoga affects the brain. A review of the science finds evidence that yoga enhances many of the same brain structures and functions that benefit from aerobic exercise.
